Announcing the preview of Software Defined Networking (SDN) on Azure Local
Big news for Azure Local customers! Starting in Azure Local version 2506, we’re excited to announce the Public Preview of Software Defined Networking (SDN) on Azure Local using the Azure Arc resource bridge. This release introduces cloud-native networking capabilities for access control at the network layer, utilizing Network Security Groups (NSGs) on Azure Local. Key highlights in this release are: 1- Centralized network management: Manage Logical networks, network interfaces, and NSGs through the Azure control plane – whether your preference is the Azure Portal, Azure Command-Line Interface (CLI), or Azure Resource Manager templates. 2- Fine-grained traffic control: Safeguard your edge workloads with policy-driven access controls by applying inbound and outbound allow/deny rules on NSGs, just as you would in Azure. 3- Seamless hybrid consistency: Reduce operational friction and accelerate your IT staff’s ramp-up on advanced networking skills by using the same familiar tools and constructs across both Azure public cloud and Azure Local. Software Defined Networking (SDN) forms the backbone of delivering Azure-style networking on-premises. Whether you’re securing enterprise applications or extending cloud-scale agility to your on-premises infrastructure, Azure Local, combined with SDN enabled by Azure Arc, offers a unified and scalable solution. Try this feature today and let us know how it transforms your networking operations! What’s New in this Preview? Here’s what you can do today with SDN enabled by Azure Arc: ✅ Run SDN Network Controller as a Failover Cluster service — no VMs required! ✅ Deploy logical networks — use VLAN-backed networks in your datacenter that integrate with SDN enabled by Azure Arc. ✅ Attach VM Network Interfaces — assign static or DHCP IPs to VMs from logical networks. ✅ Apply NSGs - create, attach, and manage NSGs directly from Azure on your logical networks (VLANs in your datacenter) and/or on the VM network interface. This enables a generic rule set for VLANs, with a crisper rule set for individual Azure Local VM network interface using a complete 5-tuple control: source and destination IP, port, and protocol. ✅ Use Default Network Policies — apply baseline security policies during VM creation for your primary NIC. Select well-known inbound ports such as HTTP (while we block everything else for you), while still allowing outbound traffic. Or select an existing NSG you already have! SDN enabled by Azure Arc (Preview) vs. SDN managed by on-premises tools Choosing Your Path: Some SDN features like virtual networks (vNETs), Load Balancers (SLBs), and Gateways are not yet supported in the SDN enabled by Azure Arc (Preview). But good news: you’ve still got options.

LocalBox delivers a streamlined, one-click sandbox experience for exploring the full power of Azure Local. With this 25H2 release, we are introducing support for Azure VM Spot pricing for the LocalBox Client VM, removed service principal dependency and transitioned to Managed Identity, added support for deploying the LocalBox Client VM and Azure Local instance in separate regions, added dedicated PowerShell modules and updated LocalBox to the Azure Local 2505 release - making it possible for you to evaluate a range of new features and enhancements that elevate the functionality, performance, and user experience. Following our LocalBox rebranding last month, today, we are thrilled to announce our second major update – LocalBox 25H2! Key Azure Local Updates Azure Local 2505 Solution Version In this release, we have updated the base image for the Azure Local nodes to the 2505 solution version. Started in the previous Azure Local 2504 release, a new operating system was introduced for Azure Local deployments. For 2505, all new deployments of Azure Local will run the new OS version 26100.4061. This unlocks several new features: Registration and Deployment Updates Starting with this release, you can now download a specific version of Azure Local software instead of just the latest version. For each upcoming release, you will be able to choose from up to the last six supported versions. Security Updates The Dynamic Root of Trust for Measurement (DRTM) is enabled by default for all new 2504 deployments running OS version 26100.3775. Azure Local VM Updates Data disk expansion - You can now expand the size of a data disk attached to an Azure Local VM. For more information, see Expand the size of a data disk attached to an Azure Local VM. Live VM migration with GPU partitioning (GPU-P) - You can now live migrate VMs with GPU-P. You can read more about what is new in Azure Local 2505 in the documentation. Jumpstart LocalBox 25H2 Updates Features Cost Optimizations with Azure Spot VM Support LocalBox now supports enabling Azure VM Spot pricing for the Client VM, allowing users to take advantage of cost savings on unused Azure capacity. This feature is ideal for workloads that can tolerate interruptions, providing an economical option for testing and dev environments. By leveraging Spot pricing, users can significantly reduce their operational costs while maintaining the flexibility and scalability offered by Azure. You may leverage the advisor on the Azure Spot Virtual Machine pricing page to estimate costs for your selected region. Here is an example for running the LocalBox Client Virtual Machine in the East US region: The new deployment parameter enableAzureSpotPricing is disabled by default, so users who wants to take advantage of this capability will need to opt-in. Visit the LocalBox FAQ to see the updated price estimates for running LocalBox in your environment. Deploying the LocalBox Client VM and Azure Local Instance in Separate Regions Our users have been sharing with us feedback around the Azure capacity requirements of deploying LocalBox, specifically when it comes to regions with sufficient compute capacity (vCPU quotas) for the VM SKU (Standard E32s v5/v6) used in LocalBox. To address this, we have now introduced a new parameter for specifying the region the Azure Local instance resources will be deployed to. In the following example, LocalBox is deployed into Norway East while the Azure Local instance is deployed into Australia East. In practice, this makes it possible to deploy LocalBox into any region where users have sufficient vCPU quotas available for the LocalBox VM SKU (Standard E32s v5/v6). Enhanced Security - Support for Azure Managed Identity We have now introduced an enhanced security posture by removing the Service Principal Names (SPN) user requirement in favor of Azure Managed Identity at deployment time. This follows the same pattern we introduced in Jumpstart ArcBox last year, and now, with Azure Local fully support deployments without an SPN, we are excited to share this update in LocalBox. Dedicated PowerShell modules Arc Jumpstart has been evolving and growing significantly since its beginning more than 5 years ago. As the code base is growing, we see the opportunity to consolidate common code and separate large scripts into modules. Our first PowerShell module, Azure.Arc.Jumpstart.Common, was moved into its own repository — and was published to the PowerShell Gallery via a GitHub Actions workflow last month. 💥 With this LocalBox release, we have also separated functions in LocalBox into the newly dedicated Azure.Arc.Jumpstart.LocalBox module. Both modules are now installed during provisioning and leveraged in automation scripts. While these modules are targeted for use in automation, it makes the scripts readable for those who want to understand the logic and potentially contribute with bugfixes or new functionality. What we’ve achieved: ✅ New repo structure for PowerShell modules ✅ CI/CD pipeline using GitHub Actions ✅ Cross-platform testing on Linux, macOS, Windows PowerShell 5.1 & 7 ✅ Published module to PowerShell Gallery ✅ Sampler module used to scaffold and streamline the module structure 🎯 This is a big step toward better reusability and scalability for PowerShell in Jumpstart scenarios. As we continue building out new use cases, having this modular foundation will keep things clean, maintainable, and extensible. Check out our SDK repository on GitHub and the modules on PowerShell Gallery. Other Quality of Life Improvements We appreciate the continued feedback from the Jumpstart community and have incorporated several smaller changes to make it easier for users to deploy LocalBox. These include, but are not limited to: Added configuration of start/shutdown settings for the nested VMs to make sure that they are shutdown properly and started in the correct order when the LocalBox Client VM is stopped and started. Moved the manual deployment steps to a separate page for clarity Added information about the Pester-tests in the Troubleshooting section, including how to open the log-file to see which tests have failed Added shortcut to Hyper-V Manager on the desktop in the LocalBox Client VM Getting started! The latest update to LocalBox not only focuses on new features but also on enhancing overall cost and deployment experience. We invite our community to explore these new features and take full advantage of the enhanced capabilities of LocalBox. Your feedback is invaluable to us, and we look forward to hearing about your experiences and insights as you navigate these new enhancements.

Public Preview Announcement - workload orchestration Introduction: As enterprises continue to scale their edge infrastructure, IT teams face growing complexity in deploying, managing, and monitoring workloads across distributed environments. Today, we are excited to announce the Public Preview of workload orchestration — a purpose-built platform that redefines configuration and deployment management across enterprise environments. Workload orchestration is designed to help you centrally manage configurations for applications deployed in diverse locations (from factories and retail stores to restaurants and hospitals) while empowering on-site teams with flexibility. Modern enterprises increasingly deploy Kubernetes-based applications at the edge, where infrastructure diversity and operational constraints are the norm. Managing these with site-specific configurations traditionally requires creating and maintaining multiple variants of the same application for different sites – a process that is costly, error-prone, and hard to scale. Workload orchestration addresses this challenge by introducing a centralized, template-driven approach to configuration. With this platform, central IT can define application configurations once and reuse them across many deployments, ensuring consistency and compliance, while still allowing site owners to adjust parameters for their local needs within controlled guardrails. The result is a significantly simplified deployment experience that maintains both central governance and localized flexibility. Key features of workload orchestration The public preview release of workload orchestration includes several key innovations and capabilities designed to simplify how IT manages complex workload deployments: Powerful Template Framework & Schema Inheritance: Define application configurations and schemas one time and reuse or extend them for multiple deployments. Workload orchestration introduces a templating framework that lets central IT teams create a single source of truth for app configurations, which can then be inherited and customized by different sites as needed. This ensures consistency across deployments and streamlines the authoring process by eliminating duplicate work. Dependent Application Management: Manage and deploy interdependent applications seamlessly using orchestrated workflows. The platform supports configuring and deploying apps with dependencies via a guided CLI or an intuitive portal experience, reducing deployment friction and minimizing errors when rolling out complex, multi-tier applications. Custom Validation Rules: Ensure every configuration is right before it’s applied. Administrators can define pre-deployment validation expressions (rules) that automatically check parameter inputs and settings. This means that when site owners customize configurations, all inputs are validated against predefined rules to prevent misconfigurations, helping to reduce rollout failures. External Validation Rules: External validation enables you to verify the solution template through an external service, such as an Azure Function or a webhook. The external validation service receives events from the workload orchestration service and can execute custom validation logic. This design pattern is commonly used when customers require complex validation rules that exceed data type and expression-based checks. It allows the implementation of business-specific validation logic, thereby minimizing runtime errors. Integrated Monitoring & Unified Control: Track and manage deployments from a single pane of glass. Workload orchestration includes an integrated monitoring dashboard that provides near real-time visibility into deployment progress and the health of orchestrated workloads. From this centralized interface, you can pause, retry, or roll back deployments as needed, with full logging and compliance visibility for all actions. Enhanced Authoring Experience (No-Code UI with RBAC): We’ve built a web-based orchestration portal that offers a no-code configuration authoring experience. Configuration managers can easily define or update application settings via an intuitive UI – comparing previous configuration revisions side by side, copying values between versions, and defining hierarchical parameters with just a few clicks. This portal is secured with role-based access control (RBAC) and full audit logging, so non-developers and local operators can safely make approved adjustments without risking security or compliance. CLI and Automation Support: For IT admins and DevOps engineers, workload orchestration provides a command-line interface (CLI) optimized for automation. This enables scripted deployments and environment bootstrapping. Power users can integrate the orchestration into CI/CD pipelines or use it to programmatically manage application lifecycles across sites, using familiar CLI commands to deploy or update configurations in bulk. Fast Onboarding and Setup: Getting started with orchestrating your edge environments is quick. The platform offers guided setup workflows to configure your organizational hierarchy of edge sites, define user roles, and set up access policies in minutes. This means you can onboard your team and prepare your edge infrastructure for orchestration without lengthy configuration processes. Architecture & Workflow: Workload orchestration is a service built with cloud and edge components. At a high level, the cloud control plane of workload orchestration provides customers and opportunity to use a dedicated resource provider to define templates centrally which WO edge agents consume and contextualize based on required customization needed at edge locations. The overall object model is embedded in Azure Resource Manager thus providing customers fine grained RBAC (Role Based Access Control) for all workload orchestration resources. The key actions to manage WO are governed by an intuitive CLI and portal experience. There is also a simplified no code experience for non-technical onsite staff for authoring, monitoring and deploying solution with contextualized configurations. Important Details & Limitations: Preview Scope: During public preview, workload orchestration supports Kubernetes-based workloads at the edge (e.g., AKS edge deployments or Arc-enabled Kubernetes clusters). Support for other types of workloads or cloud VMs is coming soon. Regions and Availability: The service is available in East US and East US2 regions during preview. Integration Requirements: Using workload orchestration with your edge Kubernetes clusters require them to be connected (e.g., via Azure Arc) for full functionality. Getting Started with workload orchestration Availability: Workload orchestration is available in public preview starting 19 th May, 2025. For access to public preview, please complete the form to get access for your subscription or share your subscription details over email at configmanager@service.microsoft.com. Once you have shared the details, the team will get back to you with an update on your request! Try it Out: We encourage you to try workload orchestration with one of your real-world scenarios. A great way to start is to pick a small application that you typically deploy to a few edge sites and use the orchestration to deploy it. Create a template for that app, define a couple of parameters (like a site name or a configuration toggle), and run a deployment to two or three test sites. This hands-on trial will let you experience first-hand how the process works and the value it provides. As you grow more comfortable, you can expand to more sites or more complex applications. Because this is a preview, feel free to experiment — you can deploy to non-production clusters or test environments to see how the orchestration fits your workflow.
